Abstract

An unknown, Gram-positive, ovoid-shaped bacterium isolated from the nose of a mouse was subjected to a polyphasic taxonomic analysis. Comparative 16S rRNA gene sequencing demonstrated that the unknown organism was a member of the family Micrococcaceae and possessed a specific phylogenetic association with Rothia dentocariosa and Stomatococcus mucilaginosus. Phenotypically, the bacterium closely resembled R. dentocariosa and S. mucilaginosus but could be distinguished from these species by biochemical tests and electrophoretic analysis of whole-cell proteins. Based on both phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified in the genus Rothia, as Rothia nasimurium sp. nov. In addition, it is proposed that S. mucilaginosus be reclassified in the genus Rothia, as Rothia mucilaginosa comb. nov.
